3 MAINTENANCE / REPAIR PROCEDURES
3.1 Preventive Maintenance
Ohaus scales are precision instruments and should be carefully handled, stored in a clean,
dry, dust-free area, and cleaned periodically. Follow these precautionary steps:

When a scale has had chemicals or liquids spilled on it, all exterior surfaces should be cleaned
as soon as possible with warm water on a damp cloth.

Do not leave a mass on the scale when the scale is not in use.

Allow time for the scale to stabilize after moving it from an area which is at a different
temperature than the area where it is to be operated. Allow one hour for each 5°F (2.7°C)
temperature change before using the scale. After temperature stabilization, allow another 20
minutes after turning the scale on, for the scale electronics to stabilize
Preventive Maintenance Checklist
The scale should be inspected and checked regularly, as follows:
1. Remove the Pan and Sub Pan to inspect and clean the area beneath the Pan.
2. Clean the outside of the scale using a damp cloth with warm water.
CAUTION
DO NOT USE CHEMICAL CLEANERS OR SOLVENTS OF ANY TYPE.
SOME CLEANERS ARE ABRASIVE A
ND MAY AFFECT THE SCALE’S FINISH.
3. Check the Power Cord for broken or damaged insulation.
4. If using the rechargeable battery and the scale malfunctions, first recharge the battery to see if
this resolves the problem.
5. Make a visual inspection for faulty connectors, wiring, and loose hardware.
Service Strategy
All parts of the Valor 1000 are designed to be replaced rather than repaired. This includes
